Title: Method of and apparatus for refrigeration
IPC: B61D27/00
Filed: 1966-08-19
Abstract: 1,131,979. Refrigerating. COLONIAL SUGAR REFINING CO. Ltd. 19 Aug., 1966 [25 Aug., 1965], No. 37201/66. Heading F4H. Pre-cooled goods are loaded into a railway carriage and the average floor air temperature is sensed for a predetermined 1st period of time by a senser 29, the information being fed through a pneumatic line 33 to a temperature controller 35. It is assumed that the floor air temperature at the end of the 1st period approximates the average temperature of the pre-cooled loaded goods. At the end of the 1st period the senser 29 is rendered inoperative, and the average ceiling air temperature is sensed by a senser 36. Whenever the ceiling temperature is higher than the terminal floor temperature the controller 35 operates to release liquid carbon dioxide from a tank 1 to refrigerate the carriage. If a manually-operated valve 37 is in the position shown, pressure transmitted from the controller 35 acts to open a valve 42 to allow carbon dioxide flow through a carriage heat-exchanger 38 to atmosphere. If the valve is in its alternative position, the controller 35 operates on a valve 48 to allow carbon dioxide flow through the exchanger 38 and thence through nozzles 39 into the carriage. A reservoir 50 accumulates gaseous carbon dioxide and its pressure is sufficient to flush any liquid carbon dioxide from the line 47 when the valve 48 is closed, thus avoiding the formation of dry ice. Timing of temperature sensing operations.- After the tank 1 has been charged through coaxial lines 2 and 6 from a source 3 a valve 16 is manually moved to its illustrated position so that carbon dioxide vaporized by a heater 14 is admitted to lines 17 and 18. Gas from line 18 passes through initially open valve 19, past a gas bleeding mechanism 21 and into a reservoir 20. When pressure in the reservoir 20 exceeds 3 p.s.i.g., a valve 22 is closed and a valve 23 is opened. This marks the beginning of the 1st temperature sensing period in which a temperature transmitter 30 is actuated by gas pressure from the line 17 which includes a pressure regulator 32, and transmits signals via a line 33 to the temperature controller 35. A non-return valve 26 opens when pressure in the reservoir 20 exceeds 60 p.s.i.g. and transmits pressure to the diaphragm of valve 19 whose closure pressure is 20 p.s.i.g. Gas supply to the reservoir thus ceases, and the reservoir pressure falls by virtue of the bleeding mechanism 21. Passage of gas by the non-return valve 26 opens a valve 27 so that gas pressure in line 18 will maintain valve 19 open while the reservoir pressure returns to normal. As the reservoir pressure falls below 3 p.s.i.g., valve 22 opens and valve 23 closes to commence sensing by the senser 36 and the consequent operation of the refrigeration system. At the end of the goods storage period valve 16 is moved to vent line 18 so that valve 19 opens and valve 27 closes. A valve 52 is provided to allow quick release of pressure in lines 25 so that premature resetting of valve 16 does not find valve 27 open and valve 19 closed.

Title: Improvements in electric circuit breakers
IPC: H01H33/825
Filed: 1962-10-02
Abstract: 951,409. Gas blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. Oct. 2, 1962 [Oct. 4, 1961], No. 37277/62. Heading H2B. In a gas blast circuit-breaker, the gas-filled (e.g. with sulphur hexafluoride) extinguishing chamber 2 is constructed as a pumping cylinder and contains a piston 7, having a gas channel 12, and a movable contact 6, having a lostmotion coupling with the piston. Actuation of an insulating linkage 8 to open contacts 5, 6 causes contact 6 to move through the piston 7 until a member 9 engages a stop 10, whereupon the contact starts to move the piston, gas being forced through the channel 12 and across the tip of contact 6, now housed fully within the piston, to extinguish the arc. Upon closing member 9 first moves to engage a stop 11, in which position the contact closes off the channel 12, and then the piston is forced back, gas being displaced through a second channel 13 and a non-return valve 14.
Patent GB-971983-A (GB)
Title: Frequency-stabilized oscillation generator system
IPC: H03L7/20
Filed: 1960-10-31
Abstract: 971,983. Automatic frequency control systems. RADIO A. I. R. APPLICATIONS INDUSTRIELLES RADIOELECTRIQUES. Oct. 31, 1960 [Nov. 6, 1959], No. 37281/60. Addition to 884,921. Heading H3A. The invention of claim 1 of the -parent Specification is modified in that the mixer 24, fed from the continuously variable oscillator 10 through the frequency multiplier 22, receives also a selected one of a series of harmonic frequencies spaced 100 kc./s. apart and derived from a crystal controlled oscillator 26. The mixer 24 output is then mixed at 29 with a selected one of crystal controlled frequencies spaced 10 kc./s. apart, the resulting output from mixer 29 being phase compared at 45 with a selected one of ten crystal-controlled 1 kc./s. spaced frequencies, and the error signal output of the phase comparator 45 effects fine frequency control of the oscillator 10 by way of a servo-control unit 50. The invention enables the output 52 of the frequency multiplier 22 to be varied in steps of 1 kc./s. over a wide frequency spectrum using only one crystal stabilized oscillator 26. The desired frequency output in kc./s. is set up on indicator elements 17 (hundreds), 39 (tens), and 48<SP>1</SP> (units) which respectively mechanically select appropriate frequencies in a " hundreds " harmonic selector generator 25, a " tens " harmonic selector generator 31 and a " units " harmonic selector or oscillator 46. The 1 mc/s. reference oscillator 26 supplies the hundreds and tens harmonic generator 25, 31 through frequency dividers 27, 32 and the units harmonic generator 46 may be similarly controlled by oscillator 26, but, as shown, an oscillator with ten control crystals is used in lieu for the generator 46. The selected hundreds harmonic is fed directly to the mixer 24, the selected tens harmonic is first added in a mixer 30 to a fixed frequency, also derived from the reference oscillator 26, before being fed to mixer 29. The selected output of oscillator 46 is fed to the phase comparator 45. Coarse adjustment of the tunable oscillator 10 is effected mechanically at 11, according to the selected frequency, for which purpose the control thereof is effected from the indicator elements 17, 39, 48<SP>1</SP> through differentials 14, 37 and appropriate reduction gearing 49, 42. As in the parent Specification, a mechanical control 20 adjusts the multiplying factor of the multiplier 22 and at the same time controls a mechanical divider 19 which introduces a transmission ratio in the mechanical control line equal to the reciprocal of the multiplying factor of multiplier 22. In a modification, Fig. 2 (not shown), the hundreds and tens harmonic generators are replaced by a single harmonic generator adjustable in steps of 10 kc./s. over the tens and hundreds range.

The belt passes over guide pulleys 26, 27, 28, 29 on the rail, a drive pulley 38 and length compensating pulleys 30, 32, 33; the pulley 30 is mounted on a bracket 6 clamped to the table and the pulleys 32, 33 to a pair of guide-rods 12 secured to the end of the rail. The drive pulley is rotated, via a gear-box 37, by an electric motor 36 mounted in a housing 35 which is secured to a bracket 5 clamped to the table. In operation, upon actuation of the motor 36, the cutting machine is moved along the rail to sever the material until it abuts a resilient buffer 23 at the end of the rail. The motor 36 continues to rotate causing the pulley 38 to slip via a clutch 39, the continued rotation of the motor shaft rotating a sprocket 40 thereon. The sprocket drives a chain 41 having a block 43 secured thereto, the block engaging an abutment bracket fixed to a pair of guide rods 11 secured to the rail. As the rail is lifted at the motor end, the opposite end is correspondingly lifted via the belt 25, the required adjustment of the length thereof being compensated by the pulley arrangement 30, 32, 33. After lifting a predetermined amount a cam 44a, Fig. 2, engages a switch 46 causing the motor 36 to be reversed and allowing the rail to move back into contact with the material. Simultaneously, the cutting machine is moved back to its starting position. In a modification, the clamp brackets 5, 6 may be replaced by carriages movable on guide rails.
